Abstract: A control device for controlling a shower waste pump, includes a housing, a pump setting, and an over-run setting. The pump setting, by way of a control element, preferably a manually adjustable potentiometer, allows selective setting of a maximum pumping capacity of the waste pump. The over-run setting, also by way of a control element, allows selective setting of an over-run period from a predetermined range during which the waste pump continues to operate after fluid flow through the waste pump has ceased or substantially ceased. The over-run setting and the pump setting together optimize operation of the waste pump, so that the over-run period of the waste pump can be set based on the selected maximum pumping capacity.

Abstract: A shower cubicle panel comprises a main panel element (14) of composite construction with at least two layers of different material, and means for interconnecting the cubicle panel (10) to an adjacent panel (10) and a shower tray (80). A connector for adjacent shower cubicle panels comprises a first part (36), a second part (38). The first part (36) has a first elongate channel portion (22b) for receiving an edge of a first shower cubicle panel, and a male connector portion (42). The second part (38) has a second elongate channel portion (22b) for receiving an edge of a second shower cubicle panel, and a female connector portion (50) substantially complementarily shaped to receive the male connector portion (42). A sealing element (40) is interposable between the first and second parts (36, 38) for preventing their disengagement.

Abstract: A pumped shower drain system (10) comprises a shower base (12), a waste water unit (14) provided on the shower base (12) and having a waste water inlet (28) and a waste water outlet (30), and a reciprocating water pump (20) for pumping water from the waste water unit (14) to a drain (22). The reciprocating water pump (20) includes: a pump housing (40) having a pump inlet (48) in liquid communication with the waste water outlet (30) of the waste water unit (14), and a pump outlet (50) in liquid communication with the drain (22); first and second inlet valve seals (56, 58) in spaced relationship; and first and second outlet valve seals (84, 86) in spaced relationship. Each set of inlet and outlet valve seals comprise different kinds of valve seals from each other, and are independently closable to close the pump inlet or outlet. Preferably, the inlet valve seals and/or the outlet valve seals have different modes of operation.

Abstract: An upward discharge waste device for a shower tray, comprises a hollow housing having a waste water inlet, a waste water outlet and a flow-channel for waste water between the waste water inlet and the waste water outlet; and a mounting element for mounting the waste device over a waste outlet of the shower tray. The flow-channel has a non-uniform transverse cross-sectional shape along the longitudinal extent from the waste water inlet and towards the waste water outlet, but has a uniform or substantially uniform transverse cross-sectional area along the longitudinal extent. A shower tray having the waste device is also provided.

Abstract: A rigid compensator device is provided for a shower screen (10) comprising a plurality of edge support elements (12) having channels (116) and a panel element (14) 5 having edges (26, 28) receivable in the channels (116) of the edge support elements (12). The compensator device (34) is folly positionable or positioned within the channel (116) of one or each said edge support element (12) of the shower screen (10) and comprises a narrow support portion (20) for receiving and directly or indirectly supporting a portion of the panel element (14) at or adjacent to the edge (26, 28) of the 0 panel element (14), a body portion (40) which is wider than the support portion (20) and which includes a panel stop element (22) at or adjacent to a rear edge or edges (50) of the compensator device (34) and spaced from the narrow support portion (20).

Abstract: A control device (10) for controlling a shower waste pump, comprises a housing (12) which is mountable to a supporting surface, pump setting means (14) located in and/or on the housing (12), and over-run setting means (16) located in and/or on the housing (12). The pump setting means (14), by way of a control element, preferably a manually adjustable potentiometer (42), allows selective setting of a maximum pumping capacity of the waste pump. The over-run setting means (16), also by way of a control element (48), allows selective setting of an over-run period from a predetermined range during which the waste pump continues to operate after fluid flow through the waste pump has ceased or substantially ceased. The over-run setting means (16) and the pump setting means (14) together can optimise operation of the waste pump, so that the over-run period of the waste pump can be set based on the selected maximum pumping capacity.

Abstract: A waste water outlet unit, for a shower tray having a drain opening, comprises a base element which is locatable on the underside of the shower tray to cover the drain opening, and a clamp element which is locatable on the topside of the shower tray and which is engageable with the base element to clamp the base element to the underside of the shower tray. The clamp element has an aperture through which waste water from the shower tray can pass into the base element, and a filter element which is positionable over the aperture and which can be removed to enable access to the interior of the unit while maintaining the engagement between the base and clamp elements.
